ADJUSTABLE INKING- GEAR.

remesa.

Application filed February 23, 1912.

To all whom/1f may concern Be it known that I, CALVIN MARTIN, a citizenof the United States, residing at Peabody, county of Essex, Commonwealthof Massachusetts, have invented certain new and useful Improvements inAdjustable Inking-Gear, of which the following is a specification.

rIhis invention relates to adjustable running gear and inking-rolls asapplied to printing machines, and, more especially, to those machineswhich are used for printing ticket slips for theaters, soda checks, etc.

The object of my invention is to provide means whereby a series ofinking rolls may be so adjusted or set that any one of them can bereplaced without necessitating resetting of the series.

In order to distribute the ink evenly over the type or electroplatewhich is used in making the printed impressions, a number of carefuladjustments are usually necessary which require the services of anexpert and considerable time. lWhenever one or more of the inking rollsis worn out or needs replacement, it has heretofore been the custom toemploy the services of this expert to again adjust the series as before.With my device, one setting suffices for every position of the inkplates or type, the new ink-rolls being mechanically guided into thesame relation with the type as those which have been removed. Under myinvention the necessarily frequent changing of an ink-roll is acomparatively simple matter and where readjust-ment is not necessary,the task can be performed by an unskilled operative. There is anotheradjustment which is related to that just described and which governs itto a certain extent. rllhe type cylinders may vary slightly in size orit may be desirable to use cylinders of distinctly di'erent diameters,due to the many sizes of tickets to be printed. I therefore preferablymount this type-cylinder so that its center of rotation may be variedwith respect to its contact drum or bed, as the case may be, thisvariance necessitating some readjustment of the inkrolls and also achange in the transmission gears. rIhe means by which these variousfeatures may be accomplished will be more fully described in thespecification which follows. In that specification and in the drawingswhich form a part of it I shall Specification of Letters Patent.

Serial No. 679,352.

make particular reference to and show and describe a form of devicewhich I have found particularly effective on a ticket press.

Throughout specication and drawings like reference numerals are employedto indicate corresponding parts and in the drawings: IVigure 1 is a sideelevation of part of a printing press embodying my invention, and F ig.2 is a partial rear elevation of Fig. 1.

The frame 1 carries, in eccentric bearings 2, the printing-cylinder 3which is adapted to receive ink from two ink-rolls 4, 4, for the purposeof printing the strip S, the latter being supported on the drum 5 whichis rotatably mounted in the frame 1.

Ink-rolls 4, 4 form part of a regular inking press series embracingdistributing rolls 6, 6 and the transfer roll 7. 'Ihe whole are mountedon arms 8, 8 which are pivotally connected to the frame 1 at 9, andoperated by the train of gears 10, 11 and 12.

A. rod 13, fast in ears on the arms 8 is adapted to be engaged by thenotches of a pair of hooks 14, 14, these hooks being pivotally mountedon the frame l at 15 and being provided with turnbuckles 16 foradjustment and flattened bosses 17 adapted to cooperate withleaf-springs 18 for holding the hooks 14 in desired positions.

The oscillating take-up roll 20, pivoted to the frame 1 at 21, isadapted to transfer the ink to the distributing roll 6 from the feedroll22, the latter being intermittently rotated within the ink-well 23.

A train of gears 25, 26, serve with the gear 10 to regulate and cont-rolthe relative movements of the printing-cylinder 3 and the variousink-rolls. The intermediate gear 25 is an idler, and in order that itmay always be adapted for speed transmission in the train 10, 25 and 26I prefer to mount it loosely on a sliding bearing 27 which is adjustablymounted at 28 upon the frame 1 so as to permit vertical adjustment.

The usual oscillating device for distributing rolls 6, 6 is indicated at30, but the general driving mechanism has been omitted as not formingpart of my invention.

The inkrolls 4-4 are each mounted in eccentric bearings in the arms 8for suitable adjustment. When therefore it is desired to replace theink-rolls 4 the hooks 14 are disengaged from the bar 13 and the frame Sswung back, thus exposing the inkrolls for ready removal or replacement.rlhis placing or replacement are all accomplished without disturbing theadjustment or if new adjustment is desired renders the same facile andeasy.

Various modications may obviously be made in the form and constructionof my device all without departingfrom the spirit of the invention ifwithin the limits of the appended claims.

W hat I, therefore, claim and desire to secure by Letters Patent is l.In a printing machine an impression cylinder, a printing cylinder inprinting contact therewith, pivoted arms adjustable relative to saidprinting cylinder and carrying suitable inking mechanism, a rodconnecting said arms, a pair of adjustable arms carrying hooks at theirree ends adapted for engagement with said connecting rod, and means foryieldingly holding said hook carrying arms in operative or inoperativeposition.

2. In a printing machine an impression cylinder, a frame, a print-ingcylinder journaled therein in printing contact with said impressioncylinder, arms swung from said frame and carrying suitable inlringmechanism, a transverse rod fast on said arms, a pair of parallel arms,carrying hooks at their free ends adapted for engagement with said rod,and means bearing against the inner ends of said hook carrying arms forCopies of this patent may he obtained for five cents each, by addressingthe Commissioner of Patents, Washington, D. CJ

yieldingly holding said arms in desired position. V

3. In a printing machine an impression cylinder, a printing cylinder inprinting contact therewith, pivoted arms carrying suitable inlringmechanism eccentrically mounted therein, a transverse rod fast on saidar1ns, a pair of parallel arms, disposed at right angles to saidtransverse rod and carryingh'ool'rs at their free ends adapted forengagement over said rod, flattened bosses formed on the inner ends ofsaid hook carryingv arms, and springs cooperating with said bosses foryieldingly holding said arms in desired position. f

4. In a printing machine, an impression cylinder, a printing cylinderadapted fory printing contact therewith and adjustable toward and fromsaid impression cylinder,` inking mechanism adjustably supportedrelative to said printing cylinder, a rod disposed transversely relativeto the Supports of said inking inechlanism,'a pair of arms adjustablerelative to said transverse rod and adapted for engagement with said rodnear each end thereof, said arms having their inner ends formed asattened bosses, and springs yieldingly engaging said bosses to hold saidarms in desired position.

In testimony whereof l aflix my signature in presence oi' two witnesses.
